FOLDING CAIVIP-STOVE SVEN.

Application filed August 23, 1924.

To all whom t may concern.'

Be it known, that RAY E. ELLIS, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, has invented new and useful Improvements in Folding Camp-Stove Ovens, of which the following is a specification.

The present invention relates to camp stoves of the portable type, and more particularly to ovens intended for use in connection with such stoves.

An object of the invention is to provide in connection with a camp stove an oven of knock-down or collapsible construction, which may be readily folded within the case for the stove or set up for use in conjunction with the stove.

A further object of the invention is to provide within the oven, and preferably secured permanently thereto, an article supporting grate or shelf, which may be readily folded with the oven structure without detachment therefrom.`

The invention also seeks to provide a deflecting plate adapted to be positioned above the burners of the stove or to be folded against one of the side walls of the oven when the latter is not in use, or is collapsed for transportation of the stove.

The invention also relates to details of construction of the oven, and has other objects, which will become apparent as the description proceeds in connection with a preferred embodiment disclosed in the accompanying drawings, wherein:

Figure 1 is a perspective of the stove and oven set up for use.

Figure 2 is a perspective showing the structure collapsed.

Figure 3 is a vertical section on the line 3-3 of Figure 4.

Figure Ll is a longitudinal section on the line 4-l of Figure 3.

Referring to the drawings for a more detailed description, l0 indicates a stove case having positioned within the same the usual burners 11 and provided with supporting legs 12 which may be folded against the bottom of the case.

The top edge of the case is provided with inturned flanges 13 which support a plate 14.- having openings to receive the burners 11.

Since the invention does not relate to the construction of the burners or of the case Serial No. 733,755.

means of a hinge joint 2O a side wall 21, the

lower edge of which is inturned to form a flange 22 adapted to rest upon the plate 111 when the oven is in operative position, as indicated in Figures 1 and 3. The oven is also provided with an end wall 23 suitably hinged at its rear edge to the back side wall 15'by means of a hinge joint 211 (Figure 3). 'lhe opposite end wall is horizontally divided to form two doors 25, 26, both of which are hinged at 27 to the side wall 15. The closure 26 has an interior fange 28 adapted to engage a complementary flange 28 formed on the side wall 23 and the door 25 has a locking flange 29 adapted to engage the top edge 26 of the closure 26.

Then in use, the oven is set up in the positionshown in Figures 1 and 3, but when the stove burners are to be employed without the oven, the latter may be swung bodily to the position indicated in dotted lines in Fig. 3 in which position itis supported by legs 30 pivoted at 30 upon the top wall 18. For supporting articles within the oven above the burners there is provided a substantially rectangular suspended from the top wall 18 by means of jointed hinge brackets 32, each of'which is formed in two sections adapted to be folded one over the other, as indicated in Figure 3, which shows the oven swung back from over the burners. The' brackets are pivotally connected to the wall hinges 19 and 20 so that both sections may be folded against the wall, together with the grate 30, when the latter is not in use. Gbviously when the oven is set up, the grate will drop automatically to position spaced from the wall 18, due to the free joint in the hinge brackets and the pivotal connections of the same with the oven wall of hinges. It will be understood, of course, that when using the term cgrate in the description and claims, there is no intention of limiting the grate or platform 31,

-collapsible therewith.v

structure in either' the claims or the speciiication to an open support for articles or one of the exact structure shown and described. y

In order to prevent direct application 'of the flame or heat from the burners to articles supported on the grate 31, a deflecting plate 33 may be positioned directly above burners and the same provided with arms pivotally connected at 35 to the wall l5 of the oven. It will be Vnoted that thisz'point of pivotal connection'issuch that 'the plate may be folded `against the wall V125 when the oven is collapsed or is moved to inoperative position, as indicated in Figure Because o-f the permanent connection of the grate 3l and `defiectin'g plate-'33 with the oven structure, there is no danger of loss `of these parts and they `do not interfere in any way with the collapsing or setting lip of the oven. Both the plate and the grate may be folded against the walls 'of the 'oven when the latter is not used and when the stove is to be. transported both parts may be. conveniently assenrbledf with the voven structure.

In Figure 2 the device is shown in knocked-down orfcollapsed state. In order to obtain this arrangement of parts, the oven is first moved to the: inoperative position shown in Figure. 3. In. 'such position both the grate and' the: d'eiiecting plate are moved against the walls and 18. respectively of the oven. The si'de Wall 21 is then f swung ldownwardrly lover the. grate and both of these walls may be tiren folded downwardly over the side wall 15. The* end walls 23 and 25, 26 may each be subsequently folded inwardlyy overv the` remaining walls which, have been super-posed. In theposition thus obtained by collapsing the 'entire oven structure, the side wall 1'5 constitutes a top for the casing, and as. will be noted from Figure 2, it is provided' with the hinged fastener 36: adapted to engage aV lug 37 on the case. i

Obviously, the invention isnot limited to the details of structurev illustrated and described, the gist of the invention being the provision of a collapsible. oven structure having iny association therewith a vdeflecting plate and grate whichk are preferablyV secured permanently to 'portions of the oven and may be freely collapsed therewith. I am aware that it isbroadly old to provide a collapsible oveny for a portable stove, but of different structure from that illustrated and described; and sov far asV I am awa-re there has neverbeen devised a construction including as ay part thereof a supporting grate permanently secured tol the oven and Nor has a deiiecting for use in conjunctionI with such a been permanently secured to theoven a manner that it does not interfere plate grate in such with the arrangement of the ovQi parts in a compact readily transportable structure such as I have provided.

I claim:

1. In va device of the vclass described, a burner carrying case and a collapsible oven structure hinged to said case, said structure including side walls, end walls, and a top wall all hingedly and permanently connected and adapted when the oven is col.-
